hello mengghee
I think your quenstion are too wide to be answered.
if you build it with the control chip, you can choose some datasheets to complete.
There are many companies have the chip,such as the Linear Technology Corporation (

TI and so on.
But if you want to built it by yourself.In my opinion,there something you need do.
Firstly,you need know how the boost converter work.It means you should study the basic knowledge about switch mode converter,especial the boost one.
Second, you need know the how to control the conveter.If you want to build a boost conveter,you should design the error amplifier, PWM comparator ,the voltage reference and so on.
I upload some basic material for you,which may be useful for you!
you also can find many useful materials in

best wishes!
